* tg3: use the DMA state API instead of the pci equivalentsFUJITA Tomonori2010-04-131-1/+1
| | | | | | | | | | | | | | | | This replace the PCI DMA state API (include/linux/pci-dma.h) with the DMA equivalents since the PCI DMA state API will be obsolete. No functional change.

| | | | | | | | | | | The maximum packet size that gets programmed into the standard producer ring control block is directly related to the packet size used to allocate packet buffers. This patch removes the redundant preprocessor constant. Signed-off-by: Matt Carlson <mcarlson@broadcom.com> Reviewed-by: Michael Chan <mchan@broadcom.com> Signed-off-by: David S.

* tg3: Optimize rx double copy testMatt Carlson2010-04-131-3/+2
| | | | | | | | | | | | | | | | | On a PCIX bus, the 5701 has a bug which requires the driver to double copy all rx packets. The rx code uses the rx_offset device member as a flag to determine if this workaround should take effect. The following patch will modify the rx_offset member such that this test will become less clear. The patch starts by integrating the workaround check into the packet length check. It rounds out the implementation by relaxing the workaround restrictions if the platform has efficient unaligned accesses.

* tg3: Unwedge stuck MSI-X vectorsMatt Carlson2010-02-131-0/+1
| | | | | | | | | | | | | | | | | | | | The previous patch changed the code so that new rx buffer submissions to the hardware stall if a new submission would overwrite data needed by an unserviced rx packet. On very busy 5717 and 57765 asic rev devices, there is a corner case where the hardware will fail to assert an MSI-X interrupt for rx traffic. If that vector's interrupt never has another reason to assert, any rx buffers held will never be serviced. If the buffers are never serviced and the hardware consumes all the available rx packets for other rx rings, deadlock will result. The most reliable and least intrusive way to work around the problem is to detect the case where new submissions would overwrite existing data and force all rx interrupt vectors to fire.

* tg3: Give MSI-X vec 1 rx backlog spaceMatt Carlson2010-02-131-1/+1
| | | | | | | | | | | | | | | | | | RSS ring 1 is responsible for submitting new rx buffers to the hardware on behalf of all the other RSS rx return rings. Up until now this ring submitted its new rx buffers to the producer ring directly. The following patch will require that this ring have a place to put backlogged rx packets. As a consequence, it can no longer submit new buffers to the producer ring. This patch adds code to allocate an extra shadow producer ring for this RSS ring and adds RSS ring 1 to the list of rings needing buffer transfers.
